The ocean buoy system comprises a solar power generation panel set, a wind generating set, a fuel cell, a control unit, a first storage battery and a second storage battery. When the target ocean buoy detects that the surrounding environment is not a target, the solar power generation device and the wind power generation device charge the two storage batteries. And when the target environment is detected and the electric quantity of the storage batteries is lower than a first electric quantity threshold value, the fuel cell starts to charge the two groups of storage batteries. The storage battery is used for supplying power to the electric load and the control unit, and the control unit is responsible for managing power distribution of the storage battery. And when the fuel cell is charged to a second electric quantity threshold value, the control unit stops the charging action of the fuel cell. Solar energy, wind power and fuel cells are combined to charge the battery pack, the stability and reliability of the power supply system are improved, and meanwhile the later maintenance cost is reduced. In addition, the strategy of automatically adjusting charging according to the electric quantity threshold can ensure the normal operation of the system and avoid overcharging.

Description

Technical Field

[0001] The present application relates to the technical field of ocean buoys, and in particular to an ocean buoy system. Background Art

[0002] Ocean buoys are devices that float on the ocean surface and are used to monitor marine environmental parameters such as wind speed, temperature, currents and waves. They are often used for meteorological and oceanographic research, marine navigation, and climate monitoring. Ocean buoys are usually equipped with various sensors and communication equipment, which require a continuous power supply to work properly. Therefore, the stability of the power supply system of ocean buoys is crucial.

[0003] The current commonly used technology is to provide energy for the battery packs of ocean buoys through solar or wind energy, but the power supply system will face limitations under extreme conditions, such as long periods of rainy weather and low wind energy. To address this challenge, it is possible to consider using wave energy or ocean current energy as a parallel power supply method. Although these new technologies conceptually provide solutions to power supply problems under severe weather conditions, they face challenges in actual operation. The operation of wave energy and ocean current energy is highly dependent on mechanical structures, and the marine environment poses challenges to the stability of mechanical structures, and maintenance work is also quite difficult. Therefore, although these alternatives seem to solve the power supply problem in theory, the reliability and maintenance costs of the mechanical structure must be considered in actual operation, which may affect the stability of the power supply system, thereby bringing new challenges and complexities.

These components are connected through the control unit respectively. The first battery and the second battery are connected to the control unit, the solar panel group, the wind generator group and the fuel cell respectively. When the environment is suitable for solar and wind power generation, the solar panel group and the wind generator group charge the battery; when it is not suitable for solar and wind power generation but the power of any battery is lower than a preset threshold, the fuel cell charges the battery. The battery supplies power to the equipment, system and control unit on the buoy, and the control unit manages the power distribution of the battery and automatically stops the charging function of the fuel cell when the fuel cell is charged to a preset threshold.

[0041] This application combines solar panels, wind turbines and fuel cells, so that the buoy can obtain electricity under various environmental conditions. Solar energy provides electricity when there is sufficient sunshine, and wind turbines supplement electricity when there is wind. When solar energy and wind energy cannot meet the power demand, fuel cells provide charging as a backup energy source to ensure that the system can continue to supply power in extreme environments.

[0042] In addition, a first storage battery and a second storage battery are provided and connected to the solar panel group, the wind turbine group and the fuel cell. This allows power storage and management to be divided into two independent batteries, thereby improving the flexibility and redundancy of energy storage. At the same time, the first storage battery and the second storage battery each supply power to the equipment and systems on the buoy, thereby increasing the redundancy and stability of the system. If one of the batteries fails, the other battery can still ensure the normal operation of the equipment.

[0043] In addition, the charging method is dynamically adjusted according to the remaining power of the battery and environmental conditions. The control unit can automatically start the fuel cell charging when the battery power is lower than the first power threshold, and interrupt the fuel cell charging when the charging reaches the second power threshold, avoiding overcharging and improving the long-term reliability of the system.

[0044] Finally, compared with power supply systems that use new technologies such as wave energy or ocean current energy, the reason why the ocean buoy system of this application is more advantageous in terms of later maintenance costs is that its design is simpler and more intelligent. This application actively manages energy distribution through a control unit and makes effective decisions based on environmental detection data, thereby avoiding unnecessary energy waste and loss, thereby reducing maintenance costs. In addition, this application uses a variety of energy supplement methods, including solar energy, wind power, and fuel cells, which improves the stability and reliability of the system, reduces the frequency of maintenance, and further reduces later maintenance costs.

Obviously, the drawings described below are only some embodiments of the present application.

[0050] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the background technology involved in the embodiments of the present application will be described below.

[0051] An ocean buoy is a structure floating on the surface of the ocean, usually used for purposes such as marking waterways, warning of dangerous areas, providing navigation information, and conducting ocean observations. A buoy usually consists of a pontoon or float supporting a column or tower, and is usually equipped with lights, signal devices, or other equipment on the top for remote identification. Ocean buoys can be divided into various types according to their functions and locations, including navigation buoys (used to guide navigation), monitoring buoys (used to measure ocean data), fishery buoys (used to locate fishing gear), etc. These buoys play an important role at sea, providing necessary support and information for navigation safety, ocean observations, and other marine activities. They are usually designed to be durable and stable to adapt to changes in the marine environment and severe weather conditions.

[0052] The stability of the power supply system of ocean buoys is crucial because these buoys rely on electricity to drive sensors and communication equipment to provide critical environmental data such as meteorological information and ocean conditions. If the power supply is interrupted, the buoy will not be able to perform its monitoring tasks, resulting in lost or inaccurate data, which will affect scientific research, weather forecasting and navigation safety.

[0053] Currently, ocean buoys often use solar energy or wind energy to power battery packs, but the power supply capacity of these methods is limited under extreme conditions of long-term rain or low wind. To address this problem, wave energy and ocean current energy have been proposed as parallel power supply methods. However, although these new technologies can theoretically solve the power supply problem caused by bad weather, they face practical challenges: wave energy and ocean current energy systems have high requirements for the stability of mechanical structures, and the marine environment is harsh on these structures and difficult to maintain. Therefore, although these alternatives are feasible in concept, in practical applications, they need to solve the problems of mechanical structure reliability and maintenance costs, which affects the overall stability of the power supply system.

[0054] In order to solve this problem, an embodiment of the present application provides an ocean buoy system, including a solar power generator set, a wind power generator set, a fuel cell, a control unit, and a first and second battery. In a non-target environment, the solar panel group and / or the wind power generator set charge the first and second batteries; in a target environment, if the power of the first battery and / or the second battery is lower than a preset threshold, the fuel cell charges the battery. The first and second batteries provide power to the power load and the control unit. The control unit is responsible for managing the power supply of the battery and automatically stops charging the fuel cell when the fuel cell charges the battery to a preset threshold. The present application uses a combination of solar energy, wind power and fuel cells to provide power to the battery pack, which can be continuously charged under different environmental conditions, thereby enhancing the stability and reliability of the system. In addition, the design of the ocean buoy power supply system of the present application is simplified and intelligent. The control unit manages energy distribution, avoids waste, enhances system stability, and adopts a variety of energy supplement methods to reduce the subsequent maintenance cost. In addition, the control unit can monitor the remaining battery power and automatically adjust the charging strategy according to the set threshold. When it is detected that the battery power is lower than the threshold, the fuel cell will be automatically started for charging, and charging will be stopped after reaching the set power, ensuring the normal operation of the system and avoiding overcharging.

[0055] In addition, compared with the new technology power supply system, the ocean buoy system of the present application significantly reduces the subsequent maintenance costs and improves the stability and reliability of the system due to its simplified intelligent design, intelligent control of energy distribution and multiple energy supplement methods.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the ocean buoy system. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] See also Figure 1 , Figure 1 A structural diagram of an ocean buoy system provided in an embodiment of the present application.

[0058] like Figure 1 The system shown includes: a solar panel group, a wind turbine generator group, a fuel cell, a control unit, and a first storage battery and a second storage battery.

[0059] The solar panel group, the wind turbine group and the fuel cell are respectively connected to the control unit; the first storage battery is respectively connected to the control unit, the solar panel group, the wind turbine group and the fuel cell; the second storage battery is respectively connected to the control unit, the solar panel group, the wind turbine group and the fuel cell.

[0060] like Figure 2 As shown, Figure 2 A schematic diagram of the structure of an ocean buoy provided in an embodiment of the present application, Figure 2 The solar panel group 30 is arranged on the solar panel laying platform 40 of the target ocean buoy; the wind power generator group 30 is arranged on the top of the target ocean buoy. The solar power generator group 30 and the wind power generator group 30 are arranged on and on the top of the solar panel laying platform 40 of the ocean buoy. This layout can maximize the use of sunlight and wind power and improve power generation efficiency.

[0061] The fuel cell is arranged in the closed base of the target ocean buoy. The fuel cell is arranged in the closed base of the target ocean buoy to prevent the fuel leakage of the fuel cell.

[0062] It should be noted that Figure 2 The base 60 in the embodiment is composed of four sectors of equal area, and the four sector bases of equal area include a closed base and an unclosed base. The closed base refers to a sector base that is not connected to the middle support tube 50 of the ocean buoy, and the unclosed base refers to a sector base that is connected to the middle support tube 50 of the ocean buoy.

[0063] When the control unit detects that the surrounding environment of the target ocean buoy is a non-target environment, the first storage battery and the second storage battery are charged by the solar panel group and / or the wind turbine generator group.

[0064] Because when the surrounding environment of the target ocean buoy is a non-target environment, the utilization efficiency of solar energy and wind energy is high, and renewable energy can be effectively used for charging, thereby reducing dependence on fuel cells, reducing costs, and extending the service life of fuel cells, while ensuring the economy and sustainability of the system. Therefore, the system will charge the first and second batteries through the solar power generation panel group and / or the wind turbine generator group in this environment.

[0065] When the control unit detects that the surrounding environment of the target ocean buoy is the target environment and the remaining battery power of the first battery and / or the remaining battery power of the second battery is less than or equal to a first power threshold, the first battery and the second battery are charged by the fuel cell.

[0066] When the control unit detects that the surrounding environment of the target ocean buoy is in the target state, and the first battery or the second battery is at or below the set capacity threshold (i.e., the first power threshold), the reason for using the fuel cell to charge it is to ensure the continuous operation and reliability of the system. The fuel cell is used to supplement the battery energy and reduce the dependence on solar energy and wind power, especially when these two energy sources cannot be used, the fuel cell provides the necessary backup energy. This will help to deal with the situation where the solar panel group and the wind turbine generator group cannot work, and provide a stable charging source for the battery to ensure the normal operation and data collection of the system at critical moments.

[0067] In one possible implementation, the size of the first power threshold may be but is not limited to 30% of the total battery capacity. The present application does not impose any specific limitation on the size of the first power threshold, and the user may adjust the size of the first power threshold according to actual needs.

[0068] It should be noted that the target environment includes environments where both solar panels and wind turbines cannot work, such as severe weather environments: such as strong storms, typhoons and other weather conditions. Under these conditions, both wind turbines and solar turbines cannot work effectively and require backup charging solutions.

[0069] In addition, when the control unit finds that the environment around the target ocean buoy meets the target environment, it is necessary to further determine whether the power of the first or second battery drops to or below the set first power threshold. If both of the above conditions are met, the fuel cell is used to charge it, which helps to optimize energy management, save resources and provide backup reserves. Delaying the use of the fuel cell until the power is close to the threshold is to avoid unnecessary consumption and ensure that the backup energy is enabled only when it is really needed. This strategy aims to effectively utilize various energy types, maximize battery life, and ensure that the system has sufficient energy support at critical moments to maintain system reliability and stability.

[0070] The first storage battery and the second storage battery are used to supply power to the electrical load and the control unit; the electrical load is the equipment and / or system installed on the target ocean buoy.

[0071] It should be noted that the power load refers to various power-consuming devices on the ocean buoy that rely on the ocean buoy for power supply, such as sensors, communication equipment, power management system navigation system and positioning system, etc.

[0072] In addition, the control unit is not classified as an electrical load in this application.

[0073] The control unit is used to control the first storage battery or the second storage battery to supply power to the electrical load.

[0074] Specifically, the control unit obtains the remaining battery power in the first battery and the remaining battery power in the second battery once at a preset time interval; if the remaining battery power in the first battery is greater than the remaining battery power in the second battery, the control unit controls the first battery to supply power to the electrical load; otherwise, the control unit controls the second battery to supply power to the electrical load.

[0075] The control unit periodically obtains the power of the first and second batteries, and when the power of the first battery is higher than that of the second battery, controls the first battery to supply power to the electrical load; otherwise, controls the second battery to supply power to the electrical load. The above balanced power supply method can ensure that the charge and discharge of the two groups of batteries are kept at an equal level, prolong the battery life and improve the system efficiency.

[0076] The control unit is further configured to interrupt the fuel cell from charging the first battery and the second battery when the fuel cell charges the remaining battery power of the first battery and the second battery to a second power threshold.

[0077] The control unit interrupts charging when the fuel cell charges the first and second batteries to a second power threshold because the ocean buoy may leave the target environment at any time. If the ocean buoy leaves the target environment, the solar panel group and / or wind turbine group can be used to charge the first and second batteries, thereby retaining more fuel to cope with the next target environment, thereby improving the flexibility and efficiency of the overall energy management and ensuring that there is sufficient reserve energy to support system operation when needed.

[0078] In one possible implementation, the size of the second power threshold may be but is not limited to 50% of the total battery capacity. The present application does not impose any specific limitation on the size of the second power threshold, and the user may adjust the size of the second power threshold according to actual needs.

[0079] In a possible implementation, the system further includes a wind turbine lifting mast.

[0080] See also Figure 2 , Figure 2 20 is a wind turbine lifting rod, one end of which is mechanically connected to the wind turbine generator set 10; the other end of which is connected to the control unit via an actuator 70. The actuator 70 is arranged in the middle and upper part of the middle support tube 50 of the target ocean buoy.

[0081] In a possible implementation, the electrical load may include, but is not limited to, a wind speed sensor, a wave height sensor, and a power generation sensor.

[0082] In a possible implementation, when the wind speed sensor detects that the duration of the current ambient wind speed being greater than or equal to the wind speed threshold is greater than or equal to the first time threshold, the control unit is further configured to determine the descent height of the wind turbine lifting mast according to the current ambient wind speed, and lower the wind turbine lifting mast based on the descent height through the actuator, so that the wind turbine lifting mast drives the wind turbine generator set to descend to the descent height; and / or,

[0083] When the wave height sensor detects that the current wave height is greater than or equal to the wave height threshold and the duration is greater than or equal to the second time threshold, the control unit is further used to determine the descent height of the wind turbine lifting rod according to the current wave height, and lower the wind turbine lifting rod based on the descent height through the actuator, so that the wind turbine lifting rod drives the wind turbine generator set to descend to the descent height; and / or,

[0084] When the power generation sensor detects that the power generation of the wind turbine generator set is greater than or equal to the third power threshold and the duration is greater than or equal to the third time threshold, the control unit is also used to determine the descent height of the wind turbine lifting rod according to the power generation of the wind turbine generator set, and lower the wind turbine lifting rod based on the descent height through the actuator, so that the wind turbine lifting rod drives the wind turbine generator set to descend to the descent height.

[0085] Among them, the duration that the current environmental wind speed is greater than or equal to the wind speed threshold is greater than or equal to the first time threshold means: the wind speed in the current environment is greater than or equal to the set wind speed threshold, and this situation lasts for a period of time exceeding the first time threshold; the duration that the current wave height is greater than or equal to the wave height threshold is greater than or equal to the second time threshold means: the current wave height is greater than or equal to the set wave height threshold, and this wave height lasts for more than the second time threshold; the duration that the power generation of the wind turbine is greater than or equal to the third power threshold is greater than or equal to the third time threshold means: the power generated by the wind turbine is greater than or equal to the set third power threshold, and this power generation level is maintained for a certain time exceeding the third time threshold.

[0086] When environmental conditions meet specific requirements, the control unit will dynamically adjust the descent height of the wind turbine mast to optimize the performance of the wind turbine generator set based on the detection results of the wind speed sensor, wave height sensor and power generation sensor. By using wind speed sensors, wave height sensors and power generation sensors, the control unit can adjust the operating status of the wind turbine generator set in real time according to environmental conditions and improve energy efficiency. The system senses environmental parameters and adjusts the descent height of the wind turbine mast accordingly, thereby ensuring that the wind turbine generator set can achieve the best power generation effect under different environmental conditions. In addition, the system adjusts according to the duration of the power threshold, which helps to maximize the use of renewable energy. Overall, this intelligent control system can improve the performance of wind power generation systems, reduce energy waste, and increase the effective use of renewable energy.

[0087] In one possible implementation, the control unit can determine the optimal descent height of the wind turbine by monitoring the current ambient wind speed and using a preset wind speed-elevator height relationship model. When the wind speed is high, the control unit will lower the height of the elevator to reduce the load on the wind turbine, and when the wind speed is low, the elevator will be raised to optimize power generation efficiency. This dynamic adjustment optimizes power generation performance and equipment safety.

[0088] In one possible implementation, the control unit can determine the optimal descent height of the wind turbine by monitoring the current wave height and using a preset wave height-elevator height relationship model. When the wave height is high, the control unit will lower the height of the elevator to reduce the swing amplitude of the wind turbine and enhance the stability of the equipment; when the wave height is low, the elevator will be raised to optimize the operating position of the equipment. This dynamic adjustment optimizes the stability of the equipment and the power generation efficiency.

[0089] In one possible implementation, the control unit can monitor the power generation of the wind turbine and use a preset power generation-elevator height relationship model to determine the optimal descent height of the wind turbine. When the power generation is high, the control unit will lower the height of the elevator to reduce the load on the wind turbine and avoid equipment overload; when the power generation is low, the elevator will be raised to improve power generation efficiency. This dynamic adjustment optimizes power generation performance and equipment safety.

[0090] In a possible implementation, the wind speed threshold may be, but is not limited to, 20 meters per second. The present application does not impose any specific limitation on the wind speed threshold, and the user may adjust the wind speed threshold according to actual needs.

[0091] In a possible implementation, the size of the wave height threshold may be but is not limited to 5 meters. The present application does not impose any specific limitation on the size of the wave height threshold, and the user may adjust the size of the wave height threshold according to actual needs.

[0092] It should be noted that, when any two of the following three situations occur, that the duration during which the current ambient wind speed is greater than or equal to the wind speed threshold is greater than or equal to the first time threshold, that the duration during which the current wave height is greater than or equal to the wave height threshold is greater than or equal to the second time threshold, and that the duration during which the power generation of the wind turbine is greater than or equal to the third power threshold is greater than or equal to the third time threshold, the control unit will simultaneously determine two descent heights; when the following three situations occur simultaneously, that the duration during which the current ambient wind speed is greater than or equal to the wind speed threshold is greater than or equal to the first time threshold, that the duration during which the current wave height is greater than or equal to the wave height threshold is greater than or equal to the second time threshold, and that the power generation of the wind turbine is greater than or equal to the third power threshold is greater than or equal to the third time threshold, the control unit will simultaneously determine three descent heights.

[0093] When the control unit determines two or three descent heights simultaneously, the wind turbine generator lifting rod is lowered by the actuator according to the descent height with the largest descent height value, so that the wind turbine generator lifting rod drives the wind turbine generator set to descend to the descent height.

[0094] In one possible implementation, the size of the third power threshold can be but is not limited to 90% of the total battery capacity. This application does not impose any specific restrictions on the size of the third power threshold, and the user can adjust the size of the third power threshold according to actual needs.

[0095] It should also be noted that the present application also does not impose any specific restrictions on the size of the first time threshold, the second time threshold, and the third time threshold. Users can adjust the size of the first time threshold, the second time threshold, and the third time threshold according to actual needs.

The vent 80 is arranged in the middle and upper position of the middle support tube 50 of the target ocean buoy; the vent includes a connecting portion 801 (the portion above the dotted line) and a vent 802 (the portion below the dotted line), and the connecting portion 801 and the vent 802 are vertically connected to each other; one end of the connecting portion 801 is connected to the middle support tube 50 of the target ocean buoy, and the other end of the connecting portion is connected to the vent 802; one end of the vent 802 is connected to the connecting portion 801, and the other end of the vent is exposed to the air, and a controllable closing valve is arranged at the other end of the vent 802; the controllable closing valve is connected to the control unit.

[0097] In a possible implementation, the length of the ventilation portion 802 may be but is not limited to 30 centimeters. The present application does not impose any specific limitation on the length of the ventilation portion 802, and the user may adjust the length of the ventilation portion 802 according to actual needs.

[0098] The vent is used to ventilate the intermediate support tube of the target ocean buoy;

[0099] The controllable closing valve is used to adjust the air flow in the vent;

[0100] The control unit is also used to control the opening and closing degree of the controllable closing valve.

[0101] To ensure the normal operation of the fuel cell, the vent should be set at the upper position of the middle support tube of the target ocean buoy. This can effectively introduce oxygen and discharge the exhaust gas generated by the combustion of fuel in the fuel cell to maintain air flow and good environmental conditions. The function of the controllable closing valve is to adjust the air flow in the vent, and adjust the airflow strength in the vent by controlling the opening and closing degree of the valve to meet specific needs. The control unit is responsible for monitoring and managing the opening and closing degree of the controllable closing valve to ensure that the air flow in the vent can be effectively controlled and adjusted, thereby realizing the precise management of the ventilation of the middle support tube of the target ocean buoy and improving the performance and stability of the system.

[0102] It should also be noted that the end of the ventilation portion 802 exposed to the air is generally downward and is generally not directed toward the sky.

[0103] In a possible implementation, the closed base of the target ocean buoy is provided with a ventilation valve and a ventilation fan; the fuel tank of the fuel cell is arranged in the closed base provided with the ventilation valve and the ventilation fan.

[0104] The closed base of the target ocean buoy is equipped with ventilation valves and ventilation fans, which are used to ensure the circulation and flow of air inside the base. The fuel cell's fuel tank is set in a closed base with ventilation valves and ventilation fans. Through this design, while ensuring ventilation inside the base, it effectively provides the required ventilation conditions for the fuel cell. The presence of ventilation valves and ventilation fans helps maintain proper ventilation in the fuel cell fuel tank, promotes air flow, maintains normal working conditions during system operation, and ensures the safety performance of the fuel cell.

[0105] In one possible implementation, the fuel stored in the fuel tank of the fuel cell may be but is not limited to methanol. The present application does not impose specific restrictions on the type of fuel stored in the fuel tank of the fuel cell. The user may adjust the type of fuel stored in the fuel tank of the fuel cell according to actual needs.

[0106] In a possible implementation, the system further includes a fuel detection device; the fuel detection device is disposed in the closed base having the fuel bin; the fuel detection device is connected to the control unit;

[0107] The fuel detection device is used to detect the fuel concentration in the closed base;

[0108] The control unit is further used to control the ventilation valve to open and control the ventilation fan to start when the fuel detection device detects that the fuel concentration is greater than or equal to the concentration threshold.

[0109] The fuel detection device is set in the closed base with the fuel tank and is connected to the control unit. The function of the fuel detection device is to detect the fuel concentration in the closed base. When the fuel detection device detects that the fuel concentration is equal to or exceeds the set concentration threshold, the control unit will take action: open the ventilation valve and start the ventilation fan. This design ensures that the system can immediately take necessary measures through the ventilation system when abnormal or dangerous fuel concentration is detected, effectively eliminating potential risks and maintaining the safe operation of the system.

[0110] See also Figure 4 , Figure 4 A structural diagram of another ocean buoy system provided in an embodiment of the present application, Figure 4 exist Figure 1 On the basis of the ocean buoy system, a remote monitoring device is added; the remote monitoring device communicates with the control unit through a General Packet Radio Service (GPRS) network communication method or a Beidou two-way communication method;

[0111] The remote monitoring device is used to transmit first buoy operation status information of the target ocean buoy to the control unit through GPRS network communication when the remaining fuel in the fuel tank of the fuel cell is greater than the fuel threshold, the target ocean buoy is placed in an offshore area, or the target ocean buoy is placed in an area with a GPRS network; the first buoy operation status information includes one or more of first control command information, position information, attitude information, and environmental data information;

[0112] The remote monitoring device is used to transmit the second buoy operation status information of the target ocean buoy to the control unit through the Beidou two-way communication mode when the remaining fuel in the fuel tank of the fuel cell is less than or equal to the fuel threshold, the target ocean buoy is placed in a remote sea area, or the target ocean buoy is placed in an area without a GPRS network; the second buoy operation status information includes one or more information of the second control command information, position information and attitude information,

[0113] The information complexity of the first control command information is higher than the information complexity of the second control command information.

[0114] Specifically, the system also includes a remote monitoring device, which communicates with the control unit through a general packet radio service GPRS network communication method or a Beidou two-way communication method. When the remaining fuel in the fuel tank of the fuel cell exceeds the fuel threshold, the target ocean buoy is located in the offshore area or has GPRS network coverage, the remote monitoring device will transmit the first type of buoy operation status information to the control unit through the GPRS network, which contains the first control command information, position information, attitude information and environmental data with high complexity. When the remaining fuel in the fuel tank of the fuel cell is less than or equal to the fuel threshold, the target ocean buoy is located in the offshore area or has no GPRS network coverage, the remote monitoring device will transmit the second type of buoy operation status information to the control unit through the Beidou two-way communication method (Beidou's two-way communication can reduce the frequency of collecting data such as position information, attitude information and environmental data information), which contains the second control command information, position information and attitude information with lower complexity. This design enables the system to select the appropriate communication method according to different situations, and flexibly adjust the complexity of the control command information according to the remaining fuel and the position of the ocean buoy, so as to realize remote monitoring and effective control of the target ocean buoy.

[0115] In a possible implementation, the fuel threshold may be, but is not limited to, 20% of the total capacity of the fuel tank. The present application does not impose any specific restrictions on the size of the fuel threshold, and the user may adjust the size of the fuel threshold according to actual needs.

[0116] In a possible implementation, when the remote monitoring device and the control unit transmit the buoy operation status information of the target ocean buoy to each other, they use a symmetric encryption algorithm or other methods to encrypt the transmitted buoy operation status information to improve data security.

[0117] In a possible implementation, both the remote monitoring device and the control unit will back up the buoy operation status information.

[0118] In a possible implementation, when the remaining fuel in the fuel tank of the fuel cell is less than or equal to a fuel threshold, the control unit is further configured to cut off power supply to all the electrical loads.

[0119] It should also be noted that the control unit itself is not considered an electrical load like other devices, and the control unit is not only responsible for managing the power supply of other electrical loads, but also assumes the communication function. Because it plays a key role in the system, even if it cuts off the power supply to all other electrical appliances or equipment, its own power supply will continue to be maintained to ensure that it can carry out normal communication and control tasks. However, in order to improve energy efficiency and reduce unnecessary power consumption, the control unit will automatically reduce its own power consumption in this case. This means that although the control unit is still working, its energy consumption will be reduced to save power while ensuring that the communication function is not affected.

[0120] When the fuel of the fuel cell is lower than the fuel threshold (eg, 20%), the control unit will start the function of reducing the electrical load, that is, the control unit will cut off the power supply to all electrical loads to achieve the purpose of extending the working time of the system.

[0121] In a possible implementation, a backup battery is provided in the control unit; the backup battery is respectively connected to the control unit, the first storage battery and the second storage battery; the backup battery is charged by the first storage battery and / or the second storage battery;

[0122] When both the first storage battery and the second storage battery are unable to supply power to the control unit, the backup battery is used to supply power to the control unit.

[0123] A backup battery is provided in the control unit, which is connected to the control unit itself, the first storage battery and the second storage battery. The backup battery can be charged by the first storage battery and / or the second storage battery. When both the first storage battery and the second storage battery are unable to provide power to the control unit, the backup battery will come into play and provide the necessary power to the control unit. This design ensures that in the event of a main power failure or unavailability, the backup battery will automatically start and maintain the normal operation of the control unit to ensure the stability and continuous performance of the system.

[0124] In a possible implementation, the electrical load further includes: an inertial navigation system and a wind speed sensor; the wind speed sensor is a laser wind sensor;

[0125] The laser wind sensor is used to detect the current ambient wind speed and the current ambient wind direction;

[0126] The inertial navigation system is used to correct the previous environment wind speed and the current environment wind direction.

[0127] The inertial navigation system can provide the motion status of the target ocean buoy, including speed and heading, which can be used to analyze and compensate for the impact of the buoy's motion on wind speed and direction measurements. The inertial navigation system uses the motion status data of the target ocean buoy to compensate for the wind speed and wind direction errors caused by the target ocean buoy's motion. For example, if the target ocean buoy is moving forward, the speed data provided by the inertial navigation system can be used to calculate the change in wind speed relative to the target ocean buoy, thereby correcting the measurement value of the laser wind sensor.

[0128] In a possible implementation, the power load further includes: a prompt unit; the prompt unit is connected to the control unit;

[0129] The target ocean buoy is provided with an activity range. When the target ocean buoy moves out of the activity range, the prompt unit generates a prompt signal and sends it to the control unit, so that the control unit transmits the prompt signal to the remote monitoring device to remind the user that the target ocean buoy may be lost or other risks due to exceeding the activity range.

[0130] It should be noted that the activity range refers to the preset geographical area where the target ocean buoy is allowed to move. The movement of the target ocean buoy within this range is considered normal, and beyond this range, a warning signal is triggered to inform the user that the buoy may be at risk, such as loss or failure.

[0131] The present application provides an ocean buoy system, including a solar panel group, a wind power generator group, a fuel cell, a control unit, and a first battery and a second battery. When the surrounding environment of the target ocean buoy is detected as a non-target environment, the first battery and the second battery are charged by the solar panel group and / or the wind power generator group; when the surrounding environment of the target ocean buoy is detected as a target environment and the remaining battery power of the first battery and / or the remaining battery power of the second battery is less than or equal to the first power threshold, the first battery and the second battery are charged by the fuel cell. The first battery and the second battery are used to supply power to the power load and the control unit. The control unit is used to control the first battery or the second battery to supply power to the power load. When the fuel cell charges the remaining battery power of the first battery and the second battery to the second power threshold, the control unit interrupts the charging action of the fuel cell for the first battery and the second battery. The ocean buoy power supply system of the present application combines solar energy, wind power and fuel cells to provide power to the battery group, ensuring that the system is continuously charged in various environments and enhancing stability and reliability. The system design is simple and intelligent, using the control unit to manage energy distribution and reduce waste, and using a variety of energy supplement methods to reduce maintenance costs. The control unit monitors the power level and automatically adjusts the charging strategy, enabling fuel cell charging when the power level is low and stopping when the set power level is reached, ensuring normal system operation and avoiding overcharging.
